Investor read

• This is a multifamily listed at $285k. Condition is rated poor.
• At list price, monthly cash flow is $3k ($41k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($7k rent vs $285k).
• Only 1 days on market — expect competitive offers; lowballing is unlikely to land.
• Local home prices are declining (-3.0%/yr); year-one equity from $2k of loan paydown is wiped out by about $9k of value loss. Plan a longer hold.
• Location reads 75/100 on livability (#157 in TX, #4,282 nationally) — a middle-class / working-renter tenant base. Strengths: cost of living A+, housing A+, health & safety A+; Watch: employment D, crime F, commute F.
• Point Isabel ISD (town): math 14% / reading 31% proficiency, ranked #756 of 826 in TX (top 92%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover.
• Zoned schools: Port Isabel J H (math 10% / reading 29%, grade F, #1,445 of 1,662 statewide, top 88%, 425 students, 84% FRL); Port Isabel H S (math 17% / reading 42%, grade F, #1,112 of 1,632 statewide, top 70%, 606 students, 82% FRL) — zoned schools average 83% FRL vs 35% district-wide (48 pts higher); higher-poverty schools than district average — tighter screening recommended.
• Watch-outs: flood insurance adds $427/mo.
• Market conditions: 254 active listings in the ZIP; 1 comparable units currently listed for rent nearby; 2,326 units permitted in Cameron County in 2024 (503 in 5+ unit buildings).
• Cameron County population projected at +3% by 2050 — modest demand growth; plan on rents tracking national, not racing it.
• At projected returns (-3.0% appreciation + 3.0% rent growth), your $80k cash investment doubles in ~3 years — after that, you're playing with house money.
• Climate carrying-cost: in FEMA flood zone AE (mandatory federal flood insurance); severe wind risk, 99% chance of damaging wind over 30y; extreme-heat days projected 7→26/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
• Cap rate 22.5% vs local median 3.4% in Port Isabel — top-decile yield for the area; either an underpriced asset or a hidden risk that comps aren't pricing in. Stress-test before assuming the spread holds.

Questions for listing agent

• Have any recent inspections been done? Can we get a copy of the seller's disclosures and any deferred-maintenance estimates?
• What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
• Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
• Schools are F-rated, which usually means shorter tenancies and higher turnover. Who's the typical renter profile here, and what's been the actual vacancy rate?
• Crime grade is F in this area — have there been break-ins, vandalism, or insurance claims at this property in the last 3 years? What carrier currently insures it and at what premium?
• What's the average days-on-market for RENTAL listings here right now (not sales)? A rising rental-DOM trend means longer vacancies and softer asking-rent achievability than the comps imply.
• What's the recent tenant-quality profile in this submarket — average credit score on applications, eviction rate, late-payment / NSF rate, and stable-employment percentage? A property-management company in the area should have these aggregated.
• How much new apartment / multifamily construction is in the pipeline within 1–3 miles? Heavy new supply (>2% of stock underway) typically softens rents 12–24 months out; light construction supports rent growth.
